Name a triangle whose two angles are equal.

Sure! To answer your question, let's break it down step by step:

Step 1: Understand the question The question is asking for the name of a triangle that has two equal angles.

Step 2: Recall triangle classifications In geometry, triangles can be classified based on their angles. There are three types of triangles based on angles: acute, obtuse, and right triangles.

Step 3: Identify the triangle with two equal angles Since the question states that two angles are equal, we can eliminate right triangles because they have one right angle (90 degrees). We are left with acute and obtuse triangles.

Step 4: Determine the name of the triangle Among acute and obtuse triangles, the triangle that has two equal angles is called an isosceles triangle.

So, the answer to your question is an isosceles triangle.
